Here's my Web2py-driven Python:
db = current.db
rows = db().select(db.person.name, distinct=db.person.name)
for row in rows:
logging.info('name: %s' % row.name)
This logs all rows from person, listing many duplicate name values.
The equivalent GQL I've tried is:
rows = gqldb.GqlQuery("SELECT DISTINCT iso31661 FROM geoPt")
for row in rows:
logging.info(row._entity['iso31661'])
and this lists each unique name once.
If I have 1,000 rows with 10 unique names then the the first example logs
1,000 names and the GQL example, 10.
Can anyone help?
